Group Buy - Led "pulse" Brake Light Bulbs

Recommended Posts

A new product - dual filament red 7443 LED bulbs that "pulse" 20 times per second for 2 seconds then illuminate normally.

For the full effect, you can also to the fogs-to-brakes modification and fit them there!

These are fitted as standard OEM to certain Mercedes models and are EU road legal. The "pulse" brake lights have been shown to reduce the braking reaction time of a following driver. Exerpt from Mercedes:

"Mercedes-Benz plans to add flashing brake lights to its vehicles in an effort to reduce rear-end collisions. The lights will initially enter production on the S-Class; the system has received approval by the European Union licensing authority. It will be followed by the CL-Class coupes.

Research by Mercedes engineers showed that driver reaction times are shortened by up to 0.2 seconds if a flashing red warning signal is used, instead of a conventional brake light during emergency braking. At 80 km/hr this reduced the stopping distance by approximately 4.4 metres, and at 100 km/hr by no less than 5.5 metres.

Mercedes-Benz tested various warning light systems and found that brake lights which light up four times as quickly as amber hazard warning flashers proved particularly effective in alerting drivers behind them. The study also revealed that switching on the hazard warning system in a dangerous situation has no significant effect on the reaction times of other drivers"

I don't have an example to show in action yet as I haven't installed my own and I'm going to be out the country for a week.

This bulb will replace the main fog/sidelight bulb in the main rear cluster. If you wants fogs-to-brakes as well, the same "pulsing" bulb will work.......and the rear of you car will look like the cabin of a 747 at take-off

So....

Rear clusters only = 1 pair

Rear clusters + fogs = 2 pairs

I presume these are for the IS and not suitable for the Mk1 GS with single (382) filament bulbs.

I'm not sure what the 382 equates to........I can get these bulbs with the 7443 wedge fitting and also the 1157 bayonet fitting (which is possibly the 382).

382 is a bayonet fitting with equally space pins but single filament so will check what equivalent in your spec is.
